Specification of Letters Patent.

JPatente-d r ce. 5,1WI3.

Application filed July 10, 1916. I Serial No. 108,296.

one object to provide a relatively small compact receptaclethat shall be arranged and adapted to receive the inner end of a flexible hose to which a cleaning tool is attached.

Another object is to provide a receptacle of the aforesaid character that shall automatically complete the circuit for the pump motor of the system when-the hose attachment is inserted ,therein. 7

In stationary vacuum cleaning apparatus,

such as is installed in residences and other buildings, there are provided a plurality of outlets to which the flexible hose may be connected. It has been mv aim to produce a flush socket receptacle that shall be simple and attractive in appearance and which shall be adapted not only to receive the hose attachment but also shall be arranged to co- 0 erate with an attachment of ordina c aracter in completing an electric circult to the pump motor of the apparatus At the same time I have particularly aimed to avoid the obstruction of the air passage or the complication of the structure.

In order that my invention may be thoroughly understood, I will now proceed to describe the same in the following specification, and then point out the novel features thereof in appended claims.

Referring to the drawings: Figure 1 is a partially sectional and partially diagrammatic elevation of vacuum cleaning apparatus, comprising a wall socket or receptacle which embodies my invention.

Fig. 2 is a transverse sectional elevation of the wall socket shown in Fig. 1,. drawn to a larger scale and taken on the line 2--2 of Fig. 3. 1

Fig. 3 is a front elevation of the same receptacle with the cover removed. J Fig. 4 is a. front elevation with the in position.

Fig. 5 is a diagrammatic view illustrating the circuit connections for the system.

In the drawings,10 represents the pump which is usually located in the basement; 11

is an electric driving motor therefor; 12 a main collecting pipe; 13 a branch therefrom, and 14 a receptacle or socket attached to the branch. A cleaning tool 15 is connected to the outer end of a flexible hose 16 which has an attachment 17 at its inner end to cooperate with the receptacle 14.

The receptacle 14 as shownmore in detail in Figs. 2, 3 and 4, comprises a metal box 18, which is attached by means of screws 19 to a screw-threaded collar 20, a block 21 of insulation within the box, a socket composed of metal terminal segments 22 and 23 and insulating segments 24, and a cover plate 25. As shown diagrammatically in F ig. 1, the terminal contact members 22and 23 are respectivelyf'connected to a supply line conductor 26 and a conductor 27 which is connected at 28 to one terminal of the motor 11. The other terminal 29 of the motor is connected to a line conductor 30.

The-arrangement of parts is such :that when the attachment 17 is inserted in the socket, a circuit is established from conductor 30 through the motor windings, conductor 27 and teglminals 23 and 22, which are bridged by t e attachment 17, to conductor 26.

A cover plate 25 has an opening 32 which fits into the opening and when closed is flush with the outer surface of the plate or cover. 25. Attached to the lid 33 which is pivoted at 34 is a block or plate 35 of insulating material which engages, when the lid is closed, the outer end of the socket and protects the terminal members from a short circuit.

switch is open and the motor circuit interis adapted to be covered by a lid 33 which rupted exce t when the terminal contacts 22 and 23 are ridged by the connector 17. In this event the branch circuit is completed, the relay switch closed, and the motor circuit established.

In either of the modifications shown and described the motor circuit is interrupted and the pump is inactive except when the flexible hose attachment is coupled to the wall receptacle; then the motor circuit is completed, the pump automatically started and the cleaning process may be continued as long as desired. It will be stopped upon the removal of the attachment from the socket.

Obviously, there will always be a number of receptacles provided in diiferent parts of the residence or building in which the cleaning apparatus is installed.

Various structural modifications may be provided within the spirit and scope of my invention, and I intend that only such limitations be imposed as are indicated in the appended claims.

What I claim is:

1. A connector for vacuum cleanin apparatus comprising a casing adapted to e connected to an intake pipe, and formed to provide a socket communicating with the pipe,

a pair of electrically independent terminal contact members, and a hose attachment connector adapted to be inserted in the socket and adapted when inserted to complete electrical circuit betweenthe contact members and. establish a fluid connection between the intake pipe and the hose.

2. A connector for Vacuum cleaning apparatus comprising a metal box or casing adapted to be attached to an intake pipe, a hollow insulating block within the box formed to provide 'a cylindrical socket constituting a continuation of the interior of the pipe, a pair of terminal contact members mechanically supported and electrically separated by the insulating block, and a hose connector adapted to be inserted in the socket, to complete electric circuit between the contact members and establish a fluid connection to the hose.

3. A connector for vacuum cleaning apparatus comprising a metal box or casing adapted'to be attached to the intake end of a cleaning pipe, a hollow insulating block within the box formed to provide a cylindrical socket constituting a continuation of the interior of the pipe, a pair of terminal contact members mounted on the insulating block and constituting spaced parts of the cylindrical socket, and a hose attachment .adapted to be inserted in the socket to complete electrical circuit between the contact members and to establish a fluid connection to the hose.

4. A connector for vacuum cleaning apparatus comprising a cleaning pipe, a casmg attached thereto, an insulating member in the casing, a socket communicating with the pipe and forming a part of the casing, a pair of electrically independent terminal contact members, and a hose attachment connector adapted to be inserted in the socket to complete electrical circuit between the contact members and to establish a fluid connection between the intake pipe and the hose.

5. A connector for vacuum cleaning apparatus comprising a cleaning pipe, a metal box or casing attached to the intake end thereof, a hollow insulating block within the box formed to provide a cylindrical socket constituting a continuation of the interior of the pipe, a pair of terminal contact members mounted on the insulating block and constituting spaced parts of the cylindrical socket, and a hose attachment adapted to be inserted in the socket to complete electrical circuit between the contact members and to establish a fluid connection to the hose.

In witness whereof, I have hereunto set my hand this 6 day of July, 1916.
